Displace

取代

You should already be familiar with the displacement channel in Cinema 4D, which raises, lowers and displaces surface points using a texture. The Displacement channel in Hair basically works the same way: Hair points are displaced in 3D using the curves in the Displacement channel (X Curve, Y Curve and Z Curve). These graphs can be used to precisely adjust the hair – as long as you are not using guides.

你应该已经熟悉C4D 中的置换通道，它使用纹理来抬高、降低和置换表面点。毛发中的位移通道基本上工作原理相同: 毛发点在3D 中使用位移通道中的曲线(x 曲线、 y 曲线和 z 曲线)进行位移。这些图表可以用来精确地调整毛发-只要你没有使用指南。

Direction

方向

Use this setting to define whether you want the X, Y and Z curves to be affected by the world or by the immovable local coordinate system.

使用这个设置来定义你是想让 x，y 和 z 曲线受到世界的影响还是受到不可移动的本地坐标系的影响。

Relative

亲属

When this setting is activated, Displace will change its unit of measure from m to %. This percentage is the amount of displacement with regard to hair length. This is important, when hair length is controlled using guides of various lengths. Let’s say you used guides to define a complete hairstyle, including sideburns, and the hair on the head is fairly long compared to that of sideburns. If, for whatever reason, you should then want to apply a relatively large displacement, the sideburns would look completely out of whack! To avoid this, activate Relative.

当这个设置被激活时，位移将把它的测量单位从米改为% 。这个百分比是相对于毛发长度的位移量。这是重要的，当毛发的长度是控制使用不同长度的指南。比方说，你用指南来定义一个完整的发型，包括鬓角，而且头上的毛发相对于鬓角来说是相当长的。如果，不管什么原因，你应该然后想申请一个相对大的位移，鬓角会看起来完全不正常！要避免这一点，激活相对。

Distance[-∞..+∞m]
Variation[-∞..+∞m]
Displace[-∞..+∞%]
Variation[-∞..+∞%]

距离[-∞ . . + ∞ m ]变差[-∞ . + ∞ m ]位移[-∞ . . + ∞% ]变差[-∞ . . + ∞% ]

Displace defines the strength of the displacement effect. If Relative is activated, the unit of measure for Displace will change from m to %. This percentage is the amount of displacement with regard to hair length.

置换决定了置换效果的强度。如果相对被激活，测量位移的单位将从 m 变为% 。这个百分比是相对于毛发长度的位移量。

Amount[0..100%]

金额[0.100% ]

Use this slider to adjust the percentage of hair that should be affected by Displacement. A value of 100% will affect all hairs.

使用这个滑块来调整毛发的百分比，应该受到位移的影响。一个100% 的值会影响所有的毛发。

X Curve
Y Curve
Z Curve

曲线

Use this setting to define the Displacement effect in 3Dimensions along the entire length of the hair. In the following images, only the X Curve setting was varied.

使用这个设置来定义沿着整个毛发长度的3维位移效果。在下面的图片中，只有 x 曲线的设置是不同的。

The curves can also have a negative value, which will cause the Displacement effect to reverse direction.

曲线也可以有一个负值，这将导致位移效果反向。

Advanced

高级

Include Root

包含 Root

If this option is active, Displacement can also be used to move the hair root. This will, though, uproot the hair and the hair will no longer be attached to the object surface. This will lead to problems when using SPD and normal material displacement because the hair will then no longer be arranged correctly on the object’s surface.

如果这个选项是活跃的，位移也可以用来移动毛发根。然而，这将连根拔起毛发，毛发将不再附着在物体表面。这将导致问题时，使用 SPD 和正常的材质位移，因为毛发将不再是正确地安排在对象的表面。

Additive

添加剂

If this option is active, an additive amplification of the Displacement effect will take place (if From Tip is not active). Each displacement of a respective hair point will be added to the previous hair point, over the entire length of the hair.

如果这个选项是活跃的，位移效果的附加放大将发生(如果从提示不活跃)。每个毛发点的位移都会加到前一个毛发点上，覆盖整个毛发长度。

The Additive option should be activated if you want to load a texture into the Direction field, otherwise the hair will not be bent.

加法选项应该被激活，如果你想加载一个纹理到方向字段，否则毛发将不会被弯曲。

From Tip

来自提示

This option, when active, will ensure an equal amount of displacement for each hair point (when Additive is active).

这个选项，当激活时，将确保相同数量的位移为每个发点(当添加剂激活)。

The resulting effect is similar to Additive being deactivated, only weaker.

由此产生的效果类似于添加剂被停用，只是更弱。

Strength

力量

Use the Strength curve to define the displacement strength (Displace setting) over the length of the hair. The curve can also be given a negative value, which will cause the Displacement effect to reverse direction.

使用强度曲线定义位移强度(置换设置)超过毛发的长度。曲线也可以给出一个负值，这将导致位移效果反方向。

Texture

纹理

A texture loaded into this field will use its grayscale values to define the Displace setting across an entire surface (an exception to this rule is the next setting, Direction).

加载到这个字段的纹理将使用它的灰度值来定义整个表面的置换设置(这个规则的一个例外是下一个设置，方向)。

Direction

方向

A texture loaded into the Direction field will use its RGB values to define the direction of the Displacement effect. The RGB values affect the direction of the hair as follows:

加载到方向字段的纹理将使用它的 RGB 值来定义位移效果的方向。RGB 值影响毛发的方向如下:

• Red - X Red-x
• Green - Y Green-y
• Blue – Z Blue-z

RGB values can affect the direction of the hair in either a positive or negative direction. Color values up to 127 will have a negative effect, whereas color values greater than 127 will have a positive effect. An equal RGB value of 127, 127, 127, for example, will result in a neutral effect and no displacement will be applied.

RGB 值可以影响毛发的方向，无论是积极或消极的方向。高达127的颜色值会产生负面影响，而高于127的颜色值会产生正面影响。一个相等的 RGB 值127,127,127，例如，将导致一个中性的效果，没有移位将适用。
